    <p>I have a <code>ListBox</code> on a form that is bound to an <code>ObservableCollection</code> of a custom type. Within each item there is a <code>ComboBox</code> bound to an enumeration type. When the window loads, all <code>ComboBox</code>es are defaulted to a certain value. When I change the <code>SelectedItem</code> for any one (from the UI, not from code), all other <code>ComboBox</code>es change to the same <code>SelectedItem</code>.</p> <p>I'm not sure what I've done wrong, here is my current XAML that is handling this.</p> <pre><code>&lt;Window.Resources&gt; &lt;ObjectDataProvider x:Key="SyncOperationValues" MethodName="GetNames" ObjectType="{x:Type sys:Enum}"&gt; &lt;ObjectDataProvider.MethodParameters&gt; &lt;x:Type TypeName="local:SyncOperationEnum" /&gt; &lt;/ObjectDataProvider.MethodParameters&gt; &lt;/ObjectDataProvider&gt; ... &lt;DataTemplate x:Key="SyncListTemplate"&gt; &lt;Grid Grid.Column="1" Grid.RowSpan="2" Margin="0,0,20,0" x:Name="olDetails" DataContext="{Binding Path=OlContact}"&gt; &lt;Grid.RowDefinitions&gt; &lt;RowDefinition /&gt; &lt;RowDefinition /&gt; &lt;RowDefinition /&gt; &lt;RowDefinition /&gt; &lt;RowDefinition /&gt; &lt;RowDefinition /&gt; &lt;RowDefinition /&gt; &lt;/Grid.RowDefinitions&gt; ... &lt;ComboBox x:Name="SyncOp" Width="120" Height="19" Margin="4,0,10,0" IsSynchronizedWithCurrentItem="True" ItemsSource="{Binding Source={StaticResource SyncOperationValues}}" SelectedItem="{Binding Operation}" VerticalAlignment="Center" /&gt; ... </code></pre> <p>and the <code>ListBox</code>:</p> <pre><code> &lt;ListBox x:Name="SyncList" ScrollViewer.HorizontalScrollBarVisibility="Hidden" ItemContainerStyle="{StaticResource StretchedContainerStyle}" ItemTemplate="{StaticResource SyncListTemplate}"&gt; ListBox&gt; </code></pre> <p>I have tried some different options, like binding to a <code>CollectionView</code>; however nothing seems to work. Can anyone point me to my mistake?</p> <p>Thanks!</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
